Abstract
A method executed by a processor in a network node positioned inside a Multiprotocol Label Switching (MPLS) core network for establishing a Point to Multipoint (P2MP) Virtual Private Network (MVPN), comprising receiving a Protocol-Independent Multicast (PIM) Join message from a node outside the MPLS core network, wherein the PIM Join message comprises a source VPN identifier (ID) and propagating the source VPN ID across a P2MP Label Switched Path (LSP) established in the MPLS core network with in-band signaling using Resource Reservation Protocol-Traffic Engineering (RSVP-TE).
